Polyethylene (PE) woven hose is commonly used in irrigation and water supply systems. Although PE woven hoses can withstand some harsh climatic conditions within a certain range, special attention is required when used in extremely cold environments below zero.

In sub-zero temperatures, water has the potential to freeze, which can cause the following problems:

1. Freeze cracking of the hose: Water expands during the cooling process. If the water in the hose freezes, it may cause the hose to break and be damaged.

2. Impaired bending performance: At low temperatures, the material of the PE woven water hose may become more fragile and easily break or deform, making it difficult to handle and operate.

3. Problems with valves and connections: In extremely cold conditions, the valves and connections on the water belt are also easily affected, and leakage or damage may occur.

If you need to use a hose in sub-zero conditions, here are some suggestions:

1. Use an anti-freeze hose: There are specially designed anti-freeze hoses that can be used in cold conditions. They usually include a built-in heating element to prevent the water from freezing.

2. Drain the hose frequently: If you must use a regular PE braided hose in cold conditions, be sure to drain the water from the hose after use to prevent freezing.

3. Protect hoses: In cold conditions, consider using insulation or burying them underground to protect hoses to reduce the risk of freezing.

In short, PE woven hoses need to be used with extreme caution in sub-zero extreme cold conditions. It is best to choose antifreeze hoses or take additional protective measures to ensure the reliability and long-term use of the system.
